MOTION-REGULATOR FOR SELF-BINDERS.

SPECIFICATION forming part of Letters Patent No. 558,191, dated April ll, 1896.

$erial No. 557,881. (No model.)

To all whom, it may concern;

Be it known that I, DANKARD I-I. LUND, a citizen of the United States,residing at Watson, in the county of Chippewa and State of Minnesota,have invented certain new and useful Improvements in Fly-Wheels orMetion-Regulators for Self-Binders; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in grain-binders which are providedwith means adapted to prevent the checking of the power generallyincident to the driving-wheel slipping upon or sinking in wet or miryground without subjecting the mechanism to strain in case the machine issuddenly started or stopped; and its novelty and advantages will befully understood from the following description and claim, when taken inconjunction with the annexed drawings, in which Figure 1 is an elevationof so much of a grain-binder as is necessary to illustrate my invention.improved friction-clutch which is designed to prevent the suddenstopping of the machine from damaging binding mechanism. Fig. 3 is atransverse section taken in the plane indicated by the line w m of Fig.2, and Fig. 4 is a plan view of the clutch.

Referring by letter to said drawings, A indicates the frame of agrain-binder, and B indicates the drive-wheel, which is fixed on one endof a shaft 0, which is also provided with a sprocket-wheel D, as shown.Intermediate mechanism,which is only partially illustrated, connects thesprocket-wheel D with the shaft I, which is provided with asprocket-wheel J, designed and adapted to transmit motion to the chainbelt G. This chain belt G passes beneath a sheave a, around asprocket-wheel h, and over a sprocket-wheel c, and it is designedthrough the I medium of the said sprocket-wheel c and the shaft H, onwhich the sprocket-Wheel is fixed, to transmit motion to the usualelevator. (Not illustrated.)

E indicates .a shaft journaled beneath the binder-deck. This shaft E isprovided with a sprocket-wheel F,which is engaged by the belt G, and itis designed through the medium of suitable interposed gearing (notillustrated) Fig. 2 is a side elevation of theto transmit motion to thebinding mechanism, which it is also not deemed necessary to illustrate.

M indicates a balance-wheel which is fixed on the shaft 1-1. This wheelM is adapted to gain such a momentum that the shaft H, and consequentlythe shaft 1, will not be affected by the slipping or sinking of thedrivingwheel B in wet soil or by the knot-tier en gaging the twine,whereby it will be perceived that the working of the binding mechanismwill be rendered smooth and even and will continue, together with themovement of the elevator, even when the movement of the drivewheelceases momentarily.

In order to prevent a sudden starting or stopping of the machine frominjuring the binding mechanism should the machine be stopped suddenly, Imount the sprocket-wheel J loosely on the shaft I, between two collarsK, which are splined or otherwise fixed on the shaft, so as to alwaysturn therewith, and provide the said wheel J on each of its sides withtwo friction-jaws L, designed to' bear against the peripheries of thecollars K, so as to enable the wheel J to normally rotate with theshaft. The friction-jaws L are provided adjacent to one end with notchesi, (see Fig. 2,) designed to engage the upper and lower horizontal armsof staples N, which are fixed in the sides of the wheel J, and at theiropposite ends said jaws are provided with apertures to receive bolts P,which are headed at one end and are threaded at their opposite ends toreceive nuts Q and have coiled springs R interposed between the nuts andone of the jaws of each pair, as shown. By reason of this constructionit will be observed that either one or both jaws of each pair may bereadily removed from the sprocket-wheel J when worn or broken and bereplaced by new ones without the aid of skilled labor or any implementother than a wrench, and it will also be observed that the frictionbetween the jaws and collars K on the shaft may be readily regulated tosuit various conditions.

It will be further observed from the foregoing that my invention may bereadily applied to binders at present in use without the employment ofskilled labor, it being simply necessary to fix the balance-wheel on theshaft H and replace the ordinary sprocket-wheel on shaft I with myimproved sprocket-wheel J and provide the said shaft with collars, as K.

Having described my invention, what I claim is In a grain-binder, thecombination of the main frame, a drive-Wheel, a shaft E, provided with asprocket-Wheel F, and adapted to transmit motion to binding mechanism, ashaft H, for driving an elevator and provided with a sprocket-wheel c, abalance-wheel fixed on said shaft H, the shaft 1, connected with thedrive-Wheel and provided with collars K, the sprocket-wheel J, looselymounted on the shaft I, between the collars K, and having staples N, onits opposite sides, friction-jaws presence of two witnesses.
